Standard 12Point Bolt
5Pieces

Now you can use premium quality ARP stainless steel or chrome moly fasteners to install most anything on a car, boat or trailer. The specially alloyed ARP 300 stainless steel and heat-treated 8740 chrome moly bolts (black oxide finish) are nominally rated at 180,000 psi tensile strength to provide a substantial extra margin of safety over Grade 8 hardware.

Whats more, you cant beat the gorgeous looks of ARPs specially polished stainless steel fasteners, and their ability to resist rust. Theyre truly maintenance free!

You can get 5-packs (washers included) of any diameter bolt from 1/4 to 1/2 or M6 to M12 in lengths ranging from 1/2 to 6, with ARP12-point heads. Matching nuts are also available

The price as well as the turn time for receiving my product was great. I placed an order late Sunday evening and I have received my order by Wednesday of that week. I still can't get over how great the price was for the bike rack I ordered compared to all of the other sites out there.

can,t believe its this cheap,probably a miss print

fast shipping, lowest prices.

Best Price and fast shipping, not bad price for the shipping cost

Great company to deal with. Had a question and called the 800 number and spoke to a person not a computer..... a real pleasure to deal with.. A plus in my book....

so far the experience has been great!

Looked my item up on Amazon and autoplicity was the lowest by far. I ordered on Sunday, it was shipped on Tuesday, and I received it on Thursday.

This was my first purchase from Autoplicity, and it was an excellent experience. They had the Motive brake bleeder adapter I needed at the best price I could find on the web. Shipping was prompt and the transaction was super smooth. Thanks!

Best price anywhere for a brand name item. Fast inexpensive shipping!
